The propeller will be folded along line 174 and by vvpassingfa'*suitablefstrap or other confining means around the unit in folded condition it is seen that it can easily be transported from placejto place. It is seen that housing willuoccupy the dotted line position indi- `cated by referencecharacter 40 with a dotted ylead-line thereto in Figure 1 when in folded condition, and the other parts willl likewise be folded as'above described.
